本文报告３７例（３７眼）采用巩膜隧道切口行白内障囊外摘除及后房型人工晶体植入术。结果表明，术后１周裸眼视力≥０．５者３０只眼（８１１％），与角膜缘切口对比，术后裸眼视力有极显著性差异（ｔ检验，Ｐ＜０．０１）。巩膜隧道切口的主要优点是术后角膜散光轻，视力恢复好。
This article reports 37 cases (37 eyes) scleral tunnel incision with extracapsular cataract extraction and posterior chamber intraocular lens implantation. The results showed that 30 eyes (81.1%) had uncorrected visual acuity of 0.5 or more at 1 week after operation. There was a significant difference in visual acuity (t-test, P <0.01) compared with limbal incision. Scleral tunnel incision is the main advantage of postoperative corneal astigmatism light, good visual acuity.
